- •
Two upflow microaerobic sludge reactors were constructed to treat MFPW.
- •
Aerobic and anaerobic activated sludge (S) were the inocula, respectively.
- •
Aerobic S was easier being accumulated than anaerobic S, only feasible for low NLR.
- •
The accumulated anaerobic AS was feasible for treating MFPW with higher NLR.
- •
An increased loading rate changed microbial community structure and removal load.
